FUS version read issue

Hello,

We are having trouble reading FUS version using STMprogrammer application.

0x20030030 always returns 0.

The interesting bit, is that SHCI_GetWirelessFwInfo() API does return 1.1.0 as FUS version as expected.

FW version is 1.5.0.

Its either issue with the documentation (address changed?), or with programmer application.

Any ideas?

./STM32_Programmer_CLI -c port=SWD mode=UR -r32 0x20030030 1

​There is no isssue except the fact that the read of the FUS version is not implemented when using the SWD port.

It works only with the USB or UART ports. You can try using one of these ports.

I understand.

Unfortunate, its a custom board with either or those interfaces available.

Any suggestion for flash sequence for SWD-only boards?

Just to try all FUS versions?

Maybe we can read the version from FUS flash address?

Thanks in advance

​You can use the batch file I created for my own usage. Just adapt the paths to your environment.
